INSULATING SPACER FOR COAXIAL CABLES Filed June 6, 1941 INVENTOR. 51/45/63 Tog/2,470
BY I
ATTORNEY Patented Sept. 30, 1947 INSULATING SPACER FOR COAXIAL CABLES Emile R. Touraton, Lyon, France, assignor to International Standard Electric Corporation, New York, N. Y., a corporation of Delaware Application June 6, 1941, Serial No. 396,950
In France May 2, 1940 3 Claims. 1
The present invention relates to improvements, changes or additions to the devices described in the main French Patent No. 852,037 for which application was filed on March 23, 1939. It relates particularly to spacing member devices for coaxial cables in which these spacing members are secured to the central conductor by a blocking system, the whole being disposed so as to be easily assembled.
The invention is explained hereunder with reference to one example of an embodiment illustrated in the appended drawings, in which:
Fig. 1 illustrates a sectional view of a coaxial cable that comprises the features of the invention;
Fig. 2 illustrates a contact member located between the spacing insulating member and the outer conductor;
Fig. 3 illustrates a member used in securing the spacing member to the central conductor.
In Fig. 1, the reference number I indicates the central conductor, and 2 the outer conductor. The insulating members 3 are fastened to the central conductor by means of a washer 8. a blocking device 5 and a screw 4.
The washer 8 is flat on one side and its other side conforms to the shape of the cylindrical central conductor on which it rests.
The blocking device 5 which is illustrated separately in Fig. 3 is provided with a slit 8 and its center has a conical shape as shown at 9. The outer surface III has a slightly rounded shape.
For the setting in place of the spacing member l, the members are disposed as shown inFig. 1, the screw 4 entering a drilled hole provided in the central conductor l.
When the members are set in place before looking. it is suiilcient to lay the spacing member l on the member 5 and rotate the latter so as to turn the screw 4. The conical head screw 4 spreads the blocking member 5 which is slitted, and causes this member 5 to exercise a strong pressure on the wall of the recess provided in the spacing member 3, thus maintaining the latter in position.
A conducting elastic member I is provided for insuring contact with the'wall of the outer conductor and avoiding the production of silent discharges.
This member I. which is shown in detail in'Fig. 2, is placed on the top of the spacing member 2, the arms ll acting a springs and a portion 12 applying against the recess provided in member 8. The spacing member is provided with a rim II and a boss H in order to avoid any possibility of displacement of member I. The surface of member I on which member 1 is applied is metallized in order to prevent the occurrence of regions of high potential gradient, and conse. quently oi discharges and eiiluvia.
The bottom surface of member 3 that is in contact with the securing members is likewise metallized.
Member 1 serves both as a spring and for compensating little irregularities in the diameters of conductors I and 2 and in the height of the insulating spacing members 3.
The insulating spacing members may be disposed at an angle of to each other, as shown in Fig. 1, and be oi. a definite number per wavelength in order to avoid the occurrence of irregularities that would result. from the effect of the capacity oi too few spacing members per wavelength.
Furthermore, the attaching oi these spacing members is eil'ected with a minimum removal of metal from the central conductor, thus further lessening any irregularities.
The coaxial cable fitted in this way is particularly suitable for use in the setting up of antenna connection circuits especially in cases when these connection circuits have to be subjected to impulses of considerable amplitude and high frequency.
} Although the invention has been described with reference to examples of embodiment, it is evident that it is by no means limited to the same and is capable of numerous modifications and adaptations without departing from its scope. 1
What is claimed is:
1. An insulating spacer for coaxial conductor pairs comprising a block 01' insulating material having a recessed opening in one end, means extending into said opening for retaining said block fixed with respect to the inner conductor of coaxial conductor pair, and spring means on the opposite end 01' said block to contact the outer conductor of said pair of conductors to assure contact regardless of minor irregularities.
2. An insulating spacer according to claim 1 wherein said spring means is made of metal. further comprising a metallic coating on the end of said block upon which'said spring is mounted.
3. An, insulating spacer according to claim 1. further comprising a metallic coating on the recessed end of said block, saidmeans extending into said opening being of conductive material.
